WCF客戶端請求返回錯誤請求（400）

Question

我的客戶端應用程序使用託管在本地IIS中的WCF Web服務。此Web服務用於上傳圖像。一旦圖像尺寸變大，它會提出錯誤的請求（400）。

客戶端被配置爲動態獲取Web服務URL。

客戶端代碼

string serviceUrl=GetUrl(); /* http://localhost:85/ImageUploaderService.svc */ 

TimeSpan timeOut = new TimeSpan(0, 30, 0); 

EndpointAddress endPoint = new EndpointAddress(serviceUrl);  


BasicHttpBinding binding = new BasicHttpBinding() 
{ 
    CloseTimeout = timeOut, 
    MaxReceivedMessageSize = 65536, 
    OpenTimeout = timeOut, 
    ReceiveTimeout = timeOut, 
    SendTimeout = timeOut, 
    MaxBufferSize = 65536, 
    MaxBufferPoolSize = 524288, 
    UseDefaultWebProxy = true, 
}; 

binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas() 
{ 
    MaxArrayLength = 64000000, 
    MaxStringContentLength = 8192, 
    MaxDepth = 32, 
    MaxNameTableCharCount = 16384, 
    MaxBytesPerRead = 4096 
}; 

client = new ImageUploaderServiceClient(binding, endPoint); 

Web服務端

<basicHttpBinding> 
    <binding maxBufferSize="64000000" maxReceivedMessageSize="64000000" maxBufferPoolSize="64000000"> 
     <readerQuotas maxDepth="64000000" maxStringContentLength="64000000" maxArrayLength="64000000" maxBytesPerRead="64000000" /> 
     <security mode="None"/> 
    </binding> 
    </basicHttpBinding> 

什麼是我做了錯誤的。請通過正確的方式指導我。

您應該增加MaxReceivedMessageSize在客戶端以及可能：

BasicHttpBinding binding = new BasicHttpBinding() 
{ 
    MaxReceivedMessageSize = 64000000, 
    MaxBufferSize = 64000000, 
    MaxBufferPoolSize = 64000000, 
// ..... 
}; 
binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas() 
{ 
    MaxArrayLength = 64000000, 
    MaxStringContentLength = 64000000, 
    MaxDepth = 64000000, 
    MaxBytesPerRead = 64000000 
}; 

我曾經有過同樣的問題 - 服務器和客戶端綁定配置應該是相同的。
